Multihomed HWN Policy Framework Signalling Delivery

Abstract

This paper presents an XML based policy framework to approach flow distribution issues for multihoming and Mobile Internet Protocol Version 6 (MIPv6) enabled Heterogeneous Wireless Networks (HWN). In such a heterogeneous environment, flow distribution policies are first defined depending on mobility decisions, service agreements and user & provider interactions. Each traffic session is coupled with an identifiable binding identification (BID) while heterogeneous interfaces are regulated by policy engines. In application layer, the protocol/algorithm agnostic Extensible Markup Language (XML) signalling is used to develop a policy management framework. The ultimate goal of the framework is to improve the Quality of Service (QoS), Quality of Experience (QoE), HWN transparency and ubiquitous connectivity.
